Lol I need glasses to solve those
Answer is NO, it does not double.
Step by step.
Equation for surface area (SA) = 2lw+2lh+2wh
If we double the length and width, making them each 2l and 2w, we then have:
2(2l x 2w) + 2(2l x h) + 2(2w x h)
= 2(4lw) + 4lh + 4wh
SA = 8lw + 4lh + 4wh
If the surface area had been doubled, we should get the equation (4lw + 4lh + 4wh) for a doubled surface area.
So no, it is not doubled.
Answer:
I think it's 2.56
you convert the 8 percent to a decimal and then you times it to 3.20
3.20×.8=2.56 (it's wrong)
=-0.75 positive divided by a negative =negative , positive divided by a positive=positive.negative divided by a negative = positive.
